MKVToolNix includes mkvmerge to build Matroska (MKV) files from other media files, mkvextract to pull out tracks and mkvinfo to show file information, together with a convenient graphical interface. With it you join several clips into one file, split a long recording by time or size, add or remove audio, subtitle and chapter tracks, and change track language and names, all without re-encoding, so quickly and with no quality loss. It suits organising recordings of lectures, meetings and long documentation. Limitation: it targets MKV as the output format and is not an editor or a re-encoder.
